The room is alright. Peter is a great guy and host. The location is good. These three things together make it a perfect place. I will tell something more about the location.
Coming from the airport, you can take the airport city link. From the last station(Phaya Thai) it is 10 minutes walking to the room. If you want to visit the old town, you can take the canalboat that you can walk to in 10 minutes. The nearest sky train station is a 5 minutes walk from the room. And if you want to use the bus, the stop is even nearer by. In that case, the bus app is usefull.
In the street you will find lots of street food, restaurants and some supermarkets. In short, I couldn't think of a better place.
